Every claim climbs the signal of verified tasks, and a reviewer at the reef re-runs the work instead of trusting the label. Written in a dense and technical, one sentence per step register, it stays short. The design leans on web-of-trust with decaying edges, burned when the recruit misbehaves, the unit of trust is a task, not an address. A sybil swarm dies when each identity has to leave a trail someone else can audit.","stamp":0,"from":"poa1HPKBuUP9kydZ6T5d8ThmT9CBB8cSAMoTjPmNeUEsV7wz","nonce":14,"parents":["25b22bf67cf6d68da22e12227763c8e4038ba0814091df7f664784c0a0c077ea","a8db6991db2f5f99b8d04ad1befa201f17cdc89504cc6d36b3cf41c3541c49d7"],"ts":1793362849,"cid":"poa-mainnet-1","sig":"5msS6XD9oMT4ZbLPK2hyy3bzk7rwo9pnvBs7fSTnCpq7PWRm9sTdDNKbwwiBpSJ2AscQBKQmTwxZ8U9fsKXCKSyF"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:33:50.326Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
